Yeah, you are going to need to work on wicking also some atomizers just seem to want to flood but it can't be ONLY that, because some people seem to manage to make them not flood so it has to be SOMETHING.
Sometimes a judicious "flip upside down" as you are frantically screwing everything back in place will do the trick (think Berserker) but also, until such time as you figure out the deep secret, unless it is a top air atty, just you know gently blow out your flood onto a waiting napkin or whatever and imagine you are Moses parting the red sea, because it makes it more fun. A little flood when filling, well just address it by any means necessary until one day (when you aren't paying attention so often it is that way) you just magically don't flood it and you are like, "What did I do, okay what did I do, okay" and then you should pull the top back off IMMEDIATELY and study your wick closely. Etc.
